There should be an option for created busses to "stick" to the right side by the main master track. If you have the 'busses group to the right' option on, it keeps them right, but also scrolls them with everything else. So for large projects you still have to scroll quite a ways to get to them. Perhaps a simple right click 'Sticky' option or something, and bam, that buss is now stuck to the right by the master. This functionality exists in Sonar as a reference.
Would be a huge time saver for something like a Drums buss, when you have 20 tracks, going to various sub-busses (Shells, Room, OH, etc), to a main Drum bus, to a master, and you just want to solo the Drums buss without scrolling all the way to the far right to get to it (as an example).
